Abstract (en)
[origin: EP1387483A2] A magnetic flux (A) produced by the current (4) of a motor is detected by means of a Hall element (11), and an infinitesimal current proportional to the actual current (4) of the motor is outputted. The outputted infinitesimal current is run through a resistor (15), and a potential difference across the resistor (15) is detected by a ӣ modulator circuit (21). The motor is subjected to feedback control based on the potential difference detected by the ӣ modulator circuit (21).
